Find a point d(x, y) such that the points a(−4, 1), b(3, 0), c(−1, −3), and d are the corners of a square.
Greeley [361]
- draw the points
- you will see thet AC has the same M as BD
- also AC = BD distance because it is a square
- calculate the M of AC
\frac{1 - ( - 3)}{ - 4 - ( - 1)}  =  \frac{4}{ - 3}  =  -  \frac{4}{3} = m
- calculate AC distance
\sqrt{ {(1 -  ( - 3))}^{2}  +  {( - 4 - ( - 1))}^{2} }  = \\   \sqrt{ {4}^{2} +  {( - 3)}^{2}  }  =  \\  \sqrt{25}  = 5 = ac
- lets say d is (x,y)
- now just make to equations with BD distance and M

What are the coordinates of the center of the circle (x-1)²+(y-2)²=2² and y=2x+2?
defon

Answer:

Compare the given equation of the circle (x - 1)² + (y -2)² = 2²

with standard form of circle: (x - h)² + (y - k)² = r²

Here, (h, k) is the center of the circle

and r is the radius of the circle.

Thus, The center of the circle is: (1, 2)

Also, for finding the point of intersections of (x - 1)² + (y -2)² = 2² and y = 2x + 2,

Substitute the value of y from equation of line in the equation of circle.

(x - 1)² + (2x + 2 - 2)² = 2²

⇒ (x - 1)² + (2x)² = 2²

⇒ x² + 1 - 2x + 4x² = 4

⇒ 5x² - 2x - 3 = 0

Applying Middle term splitting method

5x² - 5x + 3x - 3 = 0

⇒ 5x(x - 1) + 3(x - 1) = 0

⇒ (5x + 3)(x - 1) = 0

⇒ x = \frac{-3}{5} and x = 1

Thus, we get coordinates: (\frac{-3}{5} ,\frac{4}{5} ) and (1, 4)

The perimeter of an inceles triangle is 21 meters. The length of one
sdas [7]

Answer:

The sides are 6, 6 and 9

Step-by-step explanation:

Isosoles triangles have two sides the same length, s

Here the third side is 3 meters longer (s + 3)

therefor the perimeter is

s + s + (s + 3) = 21

Combine like terms

3s + 3 = 21

Subtract 3 from both sides

3s = 18

Divide both sides by 3

s = 6

s + 3 = 9

The sides are 6, 6 and 9
